To Vall whom it may concern:

Be it known that I, JAMES L. LAMB, of Trinidad, in the county of Las Animas and State of Colorado, have invented a new and 5 Improved Coal-Loading Apparatus, of which the following is a full, clear, and exact description.

This invention relates to an apparatus for loading coal into cars, and particularly for loading coal into box-cars, the invention ernbodying a trestle-way or support, on which a carriage is mounted to slide toward and from the car, the carriage supporting a conveyer mounted to turn and to be moved vertically, so that it may be adjusted to properly direct the coal.

This specification is the disclosure of one form of my invention, while the claims define the actual scope of the invention.

Figure 1 is a side elevation of the invention. Fig. 2 is a plan view thereof with parts broken away. Fig. 3 is a section taken vertically through the carrier-platform and longitudinally with the carriage. Fig. 4 is a section of the same parts on a line transverse to the carrier; and Fig. 5 is a plan view of the invention, showing it in connection with the car. y The trestle-work 6 has two horizontal rails 7, on which run the wheels 8 of the carriage 9, and mounted on the trestle and extending longitudinally with the same is a shaft 10, driven continuously bya suitable source of power. (Not shown.) Splined on the shaft 10 is a sleeve 11, at one end of which is abevelgear 12, and at the other end of which is a bevel-gear 14. The carriage 9 is provided with bearings 15, in which the shaft 10 is slidably held, such bearings moving with the carriage. The sleeve 11 is located between two of the bearings 15 and is adapted to slide with the carriage and to turn continuously with the shaft 10. A lever 16 is mounted on the carriage and connected by a collar 17 with the sleeve 11, so that upon swinging the lever the sleeve, with its gears 12 and 14, may be moved to cause either of the gears to engage with a bevel-gear 18, mounted on the shaft 19, held in bearings 20, fixed to the carriage 9. By moving the sleeve 11 to an intermediate po- 5o sition the gears 12 and 14 may be placed so that neither of the said gears will be in en gagement with the gear 18. Fixed to the shaft 19 is a spur-gear 21, which turns with the shaft 19 and moves with the carriage 9 and which engages a rack 22, fixed to the trestle-way 6. By thesemeans the revolution of the shaft 10 may, when the gears 12 and 14 are properly adjusted, be caused to revolve the shaft 19 and consequently drive the carriage 9 along the trestle-way through the medium of the spur-gear 21 and the rack 22.

Mounted on the outer end of the carriage 9 by means of a flanged hub 23, arranged to turn in the carriage, is a double-faced bevelgear 24, from the upper face of which projects a hub 25, on which a bevel-gear 26 is revolubly mounted, and xed to the top of the bevel-gear 26 are two bearings 27, in which is mounted a revoluble shaft 28, which carries loosely the arms 29 of the conveyor-frame 30, by which means the conveyor-frame is supported. The shaft 28 has a bevel-gear 31 fixed thereto, which meshes with the upper part of the bevel-gear 24, the gear 31 extending through an opening in the gear 26, as shown best in Fig. 4. The lower part of the gear 24 meshes with a bevel-gear 32, splined on the shaft 10 and connected by a link 33 with alever 34, which is fulcrumed on the carriage 9. The lever 34 in turn is connected with alink 35, which runs rearwardly and is connected to a lever 36, mounted on the carriage 9. By these means the gear 32 may be moved in and out of engagement With the lower part of the gear 24, and thus the revolution of the shaft 28 may be regulated. The conveyor-frame 30 carries an endless conveyor 37, passing around conveyer-rolls 38, held by the frame 9 and carry at their upper ends antifrictionrollers 4l, which bear down on the upper surface of the gear 26 to prevent the displacement thereof, but at the same time permit the gear 28 to revolve.

The gear 2G is driven, so as to swing the carrier or conveyer, by means o a bevel-gear 42 meshing with the gear 26 andl carried on a revoluble shaft 43, mounted on the carriage 9 and running rearwardly thereon. The shaft 43 is provided with a worm-wheel 44 at its rear end, which meshes with a worm 45, fast to a perpendicular spindle 46, mounted on the carriage 9 and having a hand-wheel 47 at its v upper end.

For adjusting the inclination of the carrier or conveyer frame I attach two arms 48 to the sides of the conveyer-frame, such arms being connected with each other by a transverse bar 49. Connected with the bar 49 is a cord 50, which passes down around a pulley 51, mounted on the top of the gear 26, and which next passes approximately horizontally around a pulley 52, carried bythe hub 25 of the wheel 24. From the pulley 52 the cord 50l carrying at one end a hand-wheel 59 and at,

the other end a worm 60, meshing with the sector 55. By means of these devices the cord 50 may be drawn in or slacked off, thus raising or lowering the carrier-frame, the same being connected to the arms 29 on the shaft 28, before described.

In using the invention the carriage 9 is projected along the trestle-way 6 until the outer end .of the carriage extends into the car 61. (Forwhich see Fig. 5.) Meanwhile the shaft 43 should have been operated to turn the gear 26, and thus adjust the carrier so that it will deliver the coal into one end of the car. The coal is fed tothe carrier 30 in the direction opposite that in which the carriage 9 is located, such feeding being done by means of a chute 62. This arrangement permits of filling one end of the car with coal, whereupon the carriage9 may be withdrawn and the chute 62 permitted to discharge the coal into the middle of the car. Meanwhile the carriage 9 may be moved back and the carrier 30 shifted so as to project into the opposite end of the car, and upon receiving the coal from the chute 6,2 the coal will fill said opposite end.

All of the elements of the apparatus are directly under the control ofthe operator, and by means of the apparatus it is possible to quickly and conveniently coal box-cars and other rolling-stock.

Having thus described my invention, I claim as new and desire to secure by Letters Patentl.
